Antique Vintage Mirrored Brass Vanity Tray 15 x 10

Vintage detailed mirror vanity tray. I believe the metal is brass. Roughly 15 x 10. Outer ornate design has no bending or breaks. Considering its age, the mirror is in great condition with light scratches visible at an angle (please see photos). The bottom appears to have been reinforced at some point with sturdy cardboard and black tape. I don't know if this used to be a frame or not. This was used on a mid-century modern dresser, and held old perfume bottles.
